ture compounded from materials, such .asv

milk, syrup and enriching agents, such as malted milk and the like,whereby smoothand finely textured beverages may be made from ingredientsnormally not readily miscible. It is further contemplated by myinvention to provide a beverage dispensing de: vice which cooperativelyserves as the means for mixing various ingredients of a concoction,suchas malted drinks, iced drinks and the like which may, at the sametime, be used as a shaker or similar beverage mixing contrivance.

Other objects of my invention reside in the provision of a stirrindgdevice cooperativel serving as a beverage 'spensing vessel who isportable and util1zable independent of motive power, such aselectricity, so that the 0 same may be carried about and used whereelectrical current is not available, to prepare a beverage. Thus, it iscontemplated by my device to prepare a stirring or mixing device wherebysuch dry materials as powdered milk, cocoa and sugar may be carriedabout and be compounded into a palatable beverage by the addition ofwater and by intimate ad mixture, using the apparatus contemplated by'my invention. Thus, by my invention, dry materials may be stored by atraveller, picnicker or camper and at places where motive power is notavailable, and merely by the addition of water, the dry materials may beformed into a beverage comprising the full equivalents of milk or thelike. It is further contemplated by my invention to provide a stirringdevice in the nature of a shaker wherein the usual operations in mixingand compounding ingredients may be facilitated 50 by the addition of arotatable stirring device,

thus hastening the mixing operation incident to shaking by a mechanicalstirring device;

Still further objects of my invention reside in the rovision of astirring device which is sanitary, neat, compact and takes up no greaterspace than a beaker or similar drinking receptacle but which may beutilized to compound various mixtures, such as milk, malted milk, cocoa,iced drinks or the like.

To attain these objects and such further objects as may appear herein orbe hereinafter pointed out, I make reference to the accompanying drawingforming a part hereof, in which- Figure 1 is a perspective view showingmy device; p A

Figure 2 is a longitudinal section taken on the line 22 of Figure 1;

Figure 3 is a section taken on the line 3-3 of Figure 2;

Figure 4 is a section taken on the line 4-4 of F1gure 2; i

- Figure 5 is a detailed sectional view taken on the line 5-5 of Figure2;

Figure 6 is a section taken on the line 6-6 of Fi re 5.

Ma g reference to the drawing, it will be observed that my devicecomprises generally a receptacle 10, preferably made of glass, in theform of a drinking beaker and a closure 11, centered and snugly fittingthereon by the aid of a ferrule 12, tightly fitting on the edge 13 ofthe receptacle and abutting against'the flange 14 formed on the exteriorof the receptacle. .The closure 11 is in the form of a housingcomprising a complemental lower section 15 and a cover member 16, withinwhich there is disposed a spring motor assembly 17. The lower section 15is formed with oflt'set flanges 18 and 19, the former serving to fitsnugly within the ferrule 12 previously described, to thus seat thehousing in the nature of a cap within the ferrule 12, the edge 13 of thevessel serving as a stop and seat for the housing. The lower offsetportion 19 is disposed for a substantial distance to the interior of thevessel and through the central portion'there is formed an orifice 20,through which there is extended the stirrer 21,- mounted upon the shaft22 and connected with the drive of the s motor b screw J r at 23. 'l h girm of the ofiset device is such that in rapid rotation it would serveas a baflie or de for the current of the bevera e as it 18 by thestirring device, to de ect the same sidewardly, thereb also guiding theascendingliquid away rom the orifice 20, through which the shaft 22passes. The ofiset portionfrom which thejflange -18 isformed serves toform a stop for the spring motor assembly, which comprises spaced dISkS24 and 25, held in this relationshi at the spacing rods 26, by the setscrews and 28, serving to engage the disks to the rods by orificesprovide t erefor.

Between the disks 24'and 25 there is journaled a spring'housin 29,provided wlth a drive gear 30, connecteg with a train of gears 31, 32and 33, mounted on the shafts 34, 35 and 36, respectively. These shaftshave suit able bearings in the plates 24 and 25, respec-v tively. Theshaft 36 is disposed through I to rotate the an orifice in the lower"disk, at which end .there is provided screw threading means enaging t eshaft The spring within the ousin 29 is anchoredto the loose shaft 37which 1s disposed above the u per disk 25 and is provided with a ratchetwheel 38, between the end bearing spring 39, which is held in positionby the set screw 40; The ratchet wheel 38 is. keyed upon the shaft 37and this is preferably accomplished by squaring the shaft 37, at 41. Apawl 42, pivoted by the screw at 43, is ressed into engagement with theratchet w eel by the spring 44, anchored by the screw at 45. A windingkey 46, havin cross arms 47 serves to engage the uare shaft 41 forrotating the shaft 37 and thereby serving to wind or tension the springwithin the housing 29; The operation is of the usual spring motor typewhereby the end of the spring aflixed to the shaft 37 remains stationaryafter winding or tightly coiling the spring, the opposite end of thespring serving the ar 30. The gear rotated by the spring W111i;restrained from rapidly moving by the train of gearspreviously describedand this is'so chosen as to'give rapid rotation to th shaft 36 at theend of the train.

I may for purposes of avoiding dissipation of thepower through thespring motor provide a braking fan 48, mounted upon the shaft 49 andgeared to the gear 32, for purposes which will become' apparent as thisdescription proceeds Connected with the gear 32, which 15 next to theend of the train, I provide a starting and I stopping member 50. Thispreferably comprises a hollow shaft fixed in the upper disk 25 andthrough which there is disposed an operating rod 51, provided at itsfree end 52 with a button or knob 53, extending beyond the section 16,through an orifice54. The lower end of the rod 51 is through theenlarged orifice 55 of the sing, which carries with it the finger 56,disengagin t angers carry 1t. I ma screw thread a stop 58 at thevery-end of t e orifice 55, which also serves as a bearin for the lowerend of the rod. Theangular disposed finger 56 is held from rotation by te slotted wall 59, the upper end of which, however,*i's given a slightangular bend at 60, for purposes which will now become apparent.

It will be observed that the rod 51 may be pulled upwardly along'thelength of the slot 59 and its movement is so governed that the end ofthe finger 56' maybe disposed ber tween the spokes of the car 32 in theextreme downward movement, t us serving as a positive brake for thisgear. I

The rod 51 may be moved upwardly until the horizontally disposed angleabuts the slot 60. A slight counter-clockwise movement will serve todispose the upper branch within the slot 60 and prevent 1ts beingdisplaced along the slot 59 by the action of the spring within thehousing 55.- When the finger is so raised and the spring motor has beenwound, the shaft 36 will be freely rotated to the full energy of thespring motor. It is preferred to apply the brake mechanism uponsubstantially the last gear of the train so that the maximum brakingaction is ob tained upon the gear directly keyed to the housing 29. Thusit will be observed that for purposes ofpreparing a beverage, the sprinmotor is wound to the desired tension, utilizing the key 46, which mayengage the squared portion of the shaft 41 previously described and forthis pu ose upper end of the housing is suitably ori ced at Liked-thekey readily disengaged from the shaft during operation. During windingof the motor, it is preferred that the finger stopping mechanism bedisposed so that the end 56 of the finger 56 is in the downward positionand between the spokes of the ear 32, thus restraining any movement of te train of gears. The mixture which is to be compounded may then bedeposited within the receptacle by lifting the entire housing'from theferrule 12, depositing the liquid in quantity as desired and indlcatedby the markings 10 preferably molded in the glass. The stirrerassociated with the housing is then replaced upon the ferrule 12.011 theedge .of the vessel 13, serving in the nature of a cap or closure. Inthis position, the knob 53 is grasped and pulled upwardly against thetension of the spring 57 drawing with it he end 56 thereof from thespokes of t e gear 32. Under these conditions, the stirrer 21 will berapidly rotated, a uniform rotation thereof being obtained by therestraining action of the braking fan. The spring motor is so chosen inrespect to the vessel so that the stirring action will be of a durationsufficient for efficiently mixing the ingredients deposited within thevessel.

Under this condition of operation, the

entire device is freely portable and the stirring action may be enhancedby shaking the entire contrivance, obtaining the combined 7 eflfect ofshaking and stirrin if so desired. It wil be observed that no ad itionalStand or fixture is necessary for maintaining the stirring mechanism inposition so that in addition to the fact that no manual operation isnecessary, the device is not dependent upon electrical current foroperation. Also, the housing serves as an eflicient means to circulatethe liquid which is stirred within the vessel as well as a closure forthe vessel during the stirring operation or shaking, if this additionalmeans is utilized to effect the mixing. In this way, it will be observedthat I have provided an efiicient, as well as portable stirring device.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is

1. A beverage mixing apparatus including a vessel, a stirrer and motordriving means therefor, a closure for said vessel forming a housing forsaid motor and formed at its lower portion with spaced flanged offsets,one to support said motor and engage the mouth of the vessel for supporting the housing and motor thereon, the other ofi'set flange belngdisposed interiorly of said vessel and formed about said stirrer to prolvide a baflle for the liquid within the vessel as it ascends in thestirring action.

2. A beverage mixing apparatus including a vessel, a stirrer and motordriving means therefor, a closure for saidve'ssel forming a housing forsaid motor and formed with spaced flanged offsets, one to support saidmotor and engage the mouth of the vessel for supporting the housingthereon, the other ofifset flange being disposed interiorly of saidvessel and formed about said stirrer to provide a bafile for the liquidwithin the vessel as it ascends in the stirring action, siad vesselbeing formed with a ferrule engaging the mouth thereof and serving asfrictional mounting for said housing, engaging one of the aforementionedofl'sets formed on the housing. g

In witness whereof I have hereunto aflixed my name this 21st day ofMarch, 1929.
